Just tried to take the quiz and the fourth question does not accept any answer as correct. I took it four times and answered with a different answer (pretty sure the correct answer is WP-Content)

You are correct (but it's the 6th question when I go through it). The answer is wp_content (lower-case wp), but it is showing as "Wrong" in the quiz (as is all 4 of the answers).
I have sent Support a message and they (or Zac Gordon ) will get that corrected.
Keep Coding :) and Thank you for pointing this out.
